Search1API MCP server

Search1API MCP Server

中文文档

The official MCP server for Search1API — web search, news, page retrieval, sitemap discovery, and trending topics in one API.

Authentication

• OAuth-aware clients can connect to the Remote MCP URL directly, then sign in and approve access in the browser.
• Existing integrations can continue to use an API key from the Search1API dashboard.
• Every MCP request — including tool discovery (initialize, tools/list) — requires a credential. Unauthenticated requests draw the OAuth challenge, which is how clients trigger sign-in; pre-connect inspection is served by the static server card instead.

Quick Start (Remote MCP)

No installation required. Configure your MCP client with the remote URL. Use OAuth when the client supports it, or provide an API key.

Authentication

Three methods are supported — use whichever your client supports:

Prefer OAuth or the Authorization header. Query-parameter credentials can be exposed in URLs, logs, and shell history.

Cursor

Install as a Cursor plugin (recommended): this repo includes Agent Plugins plugin.json + mcp.json (portable) and .cursor-plugin/plugin.json (Cursor Marketplace metadata / logo) for Remote MCP with OAuth. Submit or install from cursor.directory / the Cursor Marketplace, then sign in when prompted.

For local testing, copy the plugin files into ~/.cursor/plugins/local/search1api (plugin.json, .cursor-plugin/, mcp.json, assets/). Do not symlink from outside that directory — Cursor rejects external symlink targets.

Or configure manually:

{
  "mcpServers": {
    "search1api": {
      "url": "https://mcp.search1api.com/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_SEARCH1API_KEY"
      }
    }
  }
}

Agent Skill

The Agent Skill has moved to search1api-cli. Install it with:

npm install -g search1api-cli
npx skills add superagents-lab/search1api-cli

Local Mode (stdio)

If you prefer to run the server locally, use Node.js 20 or newer with npx — no cloning required:

{
  "mcpServers": {
    "search1api": {
      "command": "npx",
      "args": ["-y", "search1api-mcp"],
      "env": {
        "SEARCH1API_KEY": "YOUR_SEARCH1API_KEY"
      }
    }
  }
}
